So glad you found a backup to work with.
Copy the TLX design file to your hard drive (keep old copy on the stick, just in case).
Then using CSB, open and immediately FILE SAVE AS the file and give it a new name.
Edit it and save. CSB has issues when trying to edit/save a file on a USB stick but will have no problem if the file is on your own hard drive.
BEFORE you try to publish your files to your site, use your CORE FTP to DOWNLOAD the existing web pages, pictures, files, etc. Keep them on your hard drive or a usb stick JUST IN CASE you need them. Once you replace them they will be GONE so this step is a protection against GOOF.
Now EITHER:
1) Put your publishing settings info into CSB and publish directly to website host, (THIS WILL OVERWRITE ALL EXISTING PAGES), OR
2) if you need SECURE transfer for your host, you will use FTP software to do it. CoreFTP can do it and is a free program.
- Open CSB.
- PREVIEW your website, this causes CSB to "publish" your website to your own computer. You can define the folder in CSB Publishing Options/HTML Directory.
- Open CoreFTP.
- On the LOCAL side of the window, go to the folder that contains your PREVIEW files.
- The first time you do this, all files will have the same MODIFIED dates. So you will need to MANUALLY decide which files you need to upload to the website. Ex: if you changed the index.htm file, be sure to upload that page: highlight the page on the left side of the screen (LOCAL) and upload to the web server.
- After that first preview/FTP upload, it becomes EASY and quick.
- Edit in CSB. Preview. Open CoreFTP. Put your Preview folder on left (LOCAL) side and sort by Modified date. Any NEW files will go to the top of the list and you know to only upload those files. Since the changed files are in one place, it makes it VERY EASY to identify only those!
NOTE: The TLX file is a format that websites/hosts do not know. There may be a block on that format for upload, or size of file.
You can not expect to upload the TLX design file to website host and think that the browser will find the web pages. The TLX design file is compressed and MUST go through either the CSB
PUBLISH (using built-in FTP) or CSB
PREVIEW (creates your webpages on your own computer, locally) to write the HTML pages!
See this post re using FTP with CSB files. It will help you understand what you will see in the PREVIEW folder.
